It is a planning task where an agent constantly redistributes resources across a set of assets in order to achieve investment objectives and thereby maximize return. However, it remains difficult to obtain an optimal strategy in an environment as complex and dynamic as the financial market. Our article focuses on solving this stochastic control problem in order to obtain an optimal strategy that would allow us to make profitable decisions by interacting directly with the environment. To do this, we explore the power of deep reinforcement learning which differs from traditional Machine Learning by combining the task of predicting stock behavior and analyzing the optimal course of action in a single unit, thus aligning the problem of Machine Learning with the investor's objectives. As a method, we propose to use the Deep Deterministic Policy Gradient which is an off-policy algorithm and is used for environments with continuous action spaces. The obtained results demonstrate that the model achieves a higher rate of return than the strategy of “Uniform Buy and Hold” stocks and the strategy of “Buy Best Stock in last month”.","PeriodicalId":253233,"journal":{"name":"2020 6th IEEE Congress on Information Science and Technology (CiSt)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128753320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These solutions are implemented in an Asterisk AS (Application Server) server, which we will initially couple with an IMS network core. The core network used here is Clearwater with an outsourced HSS (Home Subscriber Server) from OpenIMSCore. In a second time, to couple with two IMS network cores (Clearwater). The users of each IMS network must be able to benefit from the same telephone services from the HSS. In a fourth generation context, some of our African countries are asking the telecom operators to interconnect. For this reason, we carried out the interconnection between two IMS networks allowing the users of the two IMS networks to be able to communicate with each other and benefit at the same time from the same telephone services implemented in the SA. The IMS occupies an important place in the 4G network as far as voice management is concerned. In this article, we highlight the importance of developing innovative services for the subscribers of a telecom operator. Today some countries are already starting to deploy even 5G which will offer broadband access to users. Voice is managed by the IMS network in 5G. Today, implementing services in IMS would be an advantage for tomorrow's telecom networks. Operators in African countries need to prepare themselves to take a place in the implementation of innovative services for their subscribers.","PeriodicalId":253233,"journal":{"name":"2020 6th IEEE Congress on Information Science and Technology (CiSt)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114688368","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It requires putting evolving information systems in order to exploit these massive amounts of textual data and ontologies. Hence, the need for data integration is to collect and combine them so we can provide a unified view, which analyze and visualize them for the different analytical needs of scientific researchers. In this sense, we find the Extract Transform Load (ETL) tool. It is one of the most popular approaches for data integration (DI). However, it does not take into consideration semantic data. This requirement gives birth to the Semantic ETL or ETL based on ontologies, which extends traditional ETL. Mostly known as an issue of interest to most researchers, but the latter found it difficult because of the complexity and the processing of Big Data that are characterized by 5V (Volume, Variety, Velocity, Veracity, Value). Succinctly, this paper attempts to discuss two questions such as: (1) What is the capacity of the existing Semantic ETL to manage Big Data and are they relevant in the present? (2) What is our proposal for a Semantic ETL for Big Data to overcome previous works?","PeriodicalId":253233,"journal":{"name":"2020 6th IEEE Congress on Information Science and Technology (CiSt)","volume":"246 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121440447","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
